New Data Standard for Oceanographic Research

Effective data management is paramount in oceanographic research. The ocean is a global system, and research to understand regional and global oceanographic processes often involves compiling cruise-based data from different laboratories and expeditions.

The new international data standard covers column header abbreviations, quality control flags, missing value indicators, and standardized calculation of numerous parameters. Released alongside this paper are newly developed tools to calculate some oceanographic properties, and recommendations for dissociation constants of the seawater carbon system calculations. In addition, the use of “content” instead of “concentration” is recommended for mass-based properties.

The column header abbreviation standards presented here are based on the 30-year-old Exchange format of the World Ocean Circulation Experiment (WOCE) Hydrographic Program (Joyce and Corry, 1994; Swift and Diggs, 2008) with updates and refinements by the Climate and Ocean-Variability, Predictability, and Change (CLIVAR) and the Carbon Hydrographic Data Office (CCHDO) of the Scripps Institution of Oceanography. This format has been used as a data file standard for discrete chemical oceanographic observations for several decades.

The new international data standards will facilitate data sharing, quality control, and synthesis efforts to promote climate change and ocean acidification research at regional to global scales. This product is a significant step forward in terms of (a) creating common data standards for the international oceanographic research community to streamline data management, quality control, and data product developments; and (b) bringing the subject matter expertise from the research community to the data management world.
